Two or four asynchronous RS-232, and/or
RS-485/422 serial ports - each port’s
electrical interface is jumper selectable
Each port is independently optically isolated
to 1K VAC peak to peak
Supports data communication speeds
up to 921.6 Kbps
16C650 UARTs control each port
providing 64 bytes of TxD/RxD FIFO buffers
Each RS-485 transmitter and receiver has
a jumper selectable 120 Ohm termination
resistor and also jumper selectable bias resistors
Independent port configuration with baud rates
from 50 bps to 921.6 Kbps, data bits of 5, 6, 7
or 8: stop bits of 1 or 2, and odd, even, or
stick parity
Optional RJ-45 to DB-9 male cables
Comes with comprehensive manual
and driver software. Easy to install.
Supports three RS-485 modes: Full Duplex,
Half Duplex with auto TxD echo cancellation
